OK, to close the loop on this, the solar charger is good but I was not able to make it work with the coax power-jack connector. Apparently the charger has "smart" functions that check that a battery load is connected before supplying current. And it wasn't happy being connected to the front panel power jack. So I compromised by disconnecting the battery quick-connect inside the side panel, and connecting the solar charger directly through that connector (aka SAE connector). I used an extra 10' extension cord and a reversing polarity SAE-to-SAE union, which came together in the same package. I brought the extension cord out through the pull-cord opening, so it was no trouble to close the side panel. charger: https://www.amazon.com/dp/B08K2T4RPH?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1 extension cord with adapter: https://www.amazon.com/dp/B0F2M42V7V?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1 I will see if I can attach some photos.
